MAILING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 288,424, dated November 13, 1883.

Application filed September 11, 1883. (No model.)

To. all whom it may concern:

Be it known that I, LOUIS GoDDU, of VVinchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Nailing-Machines, of which the following description, in connection with the accompany ing drawings, is a specification, like letters on the drawings representing like parts.

This present invention is an improvement on the machine represented in United States Letters Patent No. 265,227, granted to me September 26, 1882, and to which reference may be had, for herein I have deemed it necessary to show but enough of the said machine to show the application of my improvements thereto, which improvements relate, chiefly, to mechanism for separating the nails from the roadway or roadways of the chute and transferring them. to the driver-passage. In this present invention each separator, one for each roadway of the chute, is attached to a lever which causes the point of the separator to enter between the endmost nail and the one next back of it, while a pivoted transferrer and roadway-closer is held up with its edge in position to act as a continuation of the driver-passage, and after the transferrer is tipped on its pivot to uncover the end of the roadway next to it the separator, by its further movement, pushes the endmost nail off the chute and in front of the transferrer, and while the transferrer-it having struck the nail and carried it past the roadwayis being moved farther forward, the separator is made to retire from the roadway and 3 5 again come forward far enough to enter its point between the then endmost nail and the one next back of it, preparatory to the movement backward from the driver-passage of the transferrer to place it in readinessto carry forward the next nail taken from the roadway by the separator.

Figure-l shows'in elevation a sufficient por-' tionof the mechanism represented in my said patent to illustrate the manner of applying my improvements 5 Fig. 2, a right-hand side view of Fig. 1, the nail-receiver being omitted and other parts broken out; Fig. 3, a left-hand view of Fig. 1, the nail-receiver and one of the separators being omitted, the end of the chute near one separator being entirely removed, while near the other separator the part of the chute at the side of that broken away is in section. Fig. 4 is a partial section of Fig. 3 on the dotted line at m,- and Fig. 5, aperspective view of the end of the chute, to illus- 5 5 trate its two converging roadways and the groove at the end of the said chute, which groove forms a part of the driver-passage.

The head B, drum E, nail-driver bar a, stops f ffi toothed sector f tube f spring-pressed pin f and nose 0 are all substantially as in my said patent, to which reference may be had, wherein the like parts are designated by like letters.-

The chute D, supplied with nails from the nail receiver or drum E, has an attached cover, n which is joined or pivoted to the nose 0 at h, substantially as in the said patent. This chute D (shown in end view, Fig. 5) has two roadways, 2 3, which are converged, to thus throw the lower ends or points of the nails toward the groove 12 at the end of the chute and substantially at its center line, the said groove being in continuation of the driverpass'age 13 in the nose 0, so that one of the 7 transferrers a or a, which is next to be operated, a nail, 14, having been pushed off the end of the chute against the face of the said transferrer, will, in its movement inward, tip the nail from its inclined position into substantially upright position in the driver-passage, from which it will be driven by the usual driver in its descent.

The transferrer d at the right of Fig. 3 is shown as moved fully inward about its pivot 8 5 b, and in such position its vertical left-hand edge forms one side of the driver-passage.

The transferrer d, pivoted at b, is like the transferrer d, pivoted at b, and each operates, respectively, with the roadways 2 3, the pivots 0 I) b being below'the ends of the longest nails and the bottom of the chute, so that the inner edges of the transferrers, when the latter are moved into their farthest positions in the direction of the arrow 15, stand substantially 5 vertical.

The transfer cl 'hasa pivot, 16, provided with a swive1-block, 17, embraced by the forked end 18 of atransferrer-moving lever, 19, connected with a stud, 20, extended through the head B. This lever 19 has aroller-stud, 21, adapted to be actuated at times, as will be described, by the cam-face 22 of the hub 23, fast on the shaft 0, common to the said patent. The opposite transfer, d, has a like stud and swivel-block, and is actuated by a pivoted lever, 24, provided near its upper end with a roller-stud, like the one 21, shown in dotted lines, and adapted to be operated at times by the camface 25 of the hub 23. One or the other of these levers 19 and 24 will be vibrated, according to which roadway is to supply nails to the nose 0, and the particular one of these levers, the roller-stud 21 of which will be acted upon by the cam-face 22 or 25, will depend upon the position of the stops f f controlled by the sector f sleeve f and spring-pressed pin f before referred to, one of the said stops always holding one of the said levers 19 or 24, so that it will not be vibrated, its connected transferrer then closing the roadway of the chute with the end of which it co-operates.

The studs 20 and 20, which serve as the fulcra for the levers 19 and 24, and on which the said levers are fixed, have attached to them arms 27 28, joined byaspring, 29,which keeps the roller-studs of the said levers normally pressed toward the cam-faces 22 25. These studs 20 2O also serve as the fulcra for sleeves 30 31, having two arms. The sleeve 31 has an arm, 32, (see Fig. 1,) which, at its lower end, is provided with 'a separator, 33, while a second arm, 34, provided with an anti-friction roller, 35, is acted upon by the cam-face 36. (See Fig. 3.) The arm 32 is connected by spring 37 with a like arin, 38, attached to the sleeve 30, the latter being provided with a second arm, 39, having an anti-friction roll, 40, acted upon by the cam-face 41. The arm 38 has a separator, 42, whichin construction and operation is the same as the separator more fully described in my application, Case A, No. 106,133, filed concurrently with this. The separators act, as therein described, to push singly each endmost nail from its roadway and the end of the chute when the said roadway is uncovered by the backward movement of its cooperating transferrer.

I claim 1. The chute provided with a roadway for nails or fastenings,and a nose having a driverpassage, combined with a separator, and with a transferrer pivoted below the lower ends of the nails, substantially as described.

2. In a nailingmachine, a chute provided with two roadways converging at their bottoms toincline the points of the nails toward, the driver-passage, combined with the separators, and the two transferrers pivoted below the ends of the nails and adapted,when brought together, to close one roadway and form a part of the driver passage, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
